Which One of the following is not a cause of secondary Postpaum Haemorrhage?
**Core Concept**
Secondary postpartum hemorrhage (PPH) is a life-threatening condition that occurs after the initial 24 hours following childbirth. It is a leading cause of maternal mortality worldwide. The causes of secondary PPH can be broadly classified into uterine atony, retained products of conception, coagulopathy, and trauma.
**Why the Correct Answer is Right**
Secondary PPH is often caused by uterine atony (the failure of the uterus to contract), retained products of conception (placental or fetal tissue remaining inside the uterus), coagulopathy (blood clotting disorders), or trauma to the uterus or birth canal. Uterine atony is the most common cause, accounting for up to 80% of cases. Retained products of conception can lead to infection and further bleeding. Coagulopathy can be due to various factors such as bleeding disorders, anticoagulant use, or disseminated intravascular coagulation (DIC). Trauma can occur due to instrumental delivery, cesarean section, or other forms of uterine manipulation.
